Help to identify a viking sword

[sioume]

Hello everybody,
Back after a long time , I will appreciate some clear informations about a so called viking sword type. I know there are good specialists on this website !

The sword measures 91 cm , weights 1,4 kg, with a rather deep inscription on the blade , unreadable except the end "+....DC+ ?" and was bought a long time ago to a french antiquarian.
To my modest knowledges it seems to be a genuine piece considering the corrosion, patina, howeverwhat makes me interrogative is the pommel.
Some collectors said to me it is a L or Q Petersen type but the pommel of my sword is quite curved and seems to be more a "O" Type...
Also I red on the web that this type is common in Norway which is strange because I thought that curved pommels were from anglo-saxon origins.
Riveted the pommel and pommel-guard together ( like on my sword) isn't it also an anglo-saxon technique ?

Thanks for helping me to identify the origin and datation of this sword
All the best
